Smart Money Signals — NBBK

Based on 174 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 10 quarters in a row

last 6Q
For 10 consecutive quarters, more hedge funds added NBBK than sold it. That's a consistent pattern of professional buying — not a one-time trade. When institutions keep buying quarter after quarter, it usually means they see a multi-year opportunity, not just a short-term momentum flip.
🏔️

At the ownership peak (100% of max)

100% of all-time peak
174 hedge funds hold NBBK right now — the highest count in 3.0 years. When ownership is this concentrated, any bad news can trigger a chain reaction: one big fund sells, others follow. This is a classic 'crowded trade' — high popularity doesn't equal safety.
🚀

Fast accumulation — +40% more funds vs a year ago

fund count last 6Q
+50 new funds entered over the past year (+40% YoY). That's a rapid rush of institutional money. Fast accumulation often signals a major thesis — but it also means the stock could fall quickly if that thesis breaks.
🟢

More buyers than sellers — 60% buying

95 buying64 selling
Last quarter: 95 funds were net buyers (31 opened a brand new position + 64 added to an existing one). Only 64 were sellers (45 trimmed + 19 sold completely). A clear majority buying is a strong confirmation signal.
➡️

Steady new buyers — ~31 new funds per quarter

new funds entering per quarter
Funds opening this position for the first time: 20 → 27 → 35 → 31. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔄

Mostly new holders — 38% entered in last year

■ 24% conviction (2yr+) ■ 39% medium ■ 38% new
Only 41 funds (24%) have held >2 years. The majority of current holders are relatively new to the position. New holders tend to sell faster when prices drop — a shallow conviction base that could amplify any sell-off.
📈

Growing discovery — still being found

22 → 20 → 27 → 35 → 31 new funds/Q
New funds entering each quarter: 20 → 27 → 35 → 31. A growing number of institutions are discovering NBBK each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
📊

Mixed cohorts — 9% veterans, 45% new entrants

■ 9% veterans ■ 46% 1-2yr ■ 45% new
Of 177 current holders: 16 (9%) held 2+ years, 81 held 1–2 years, 80 (45%) entered in the past year. Balanced distribution — some institutional memory, some recent momentum buyers.
✅

Strong quality — 34% AUM from major funds

34% from top-100 AUM funds
44 of 174 holders rank in the top 100 by AUM, accounting for 34% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
4.5
out of 10
Moderate Exit Risk
Exit risk score 4.5/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.

Methodology note: these Smart Money cards use consecutive 13F disclosure snapshots, not trade-by-trade execution data. "Buying", "selling", "new holders", and "trimmed" refer to quarter-over-quarter changes in reported holders, aggregate shares, or disclosed position values between filings. They are useful for ownership regime analysis and crowding, but they do not imply exact trade timing on the filing date.
